The hidden layer of SEO
Crawl errors, duplicate pages and slow templates can keep valuable content out of search.
We prioritize technical fixes by impact, work with your developers and validate the changes.
Technical SEO isn't a list of every warning a tool can produce. We focus on the issues that affect your priority pages, explain why they matter in plain language, and work alongside your developers until each fix is confirmed.
What the work includes
The proposal defines site sections, environments and who implements each fix. Every workstream ends with a concrete output—not a raw tool export.
Make sure search engines can reach the pages that matter—and spend less time on those that don't.

Inside the review
Each ticket explains what's wrong, where it happens and how we'll know it's fixed.

Measurement you can trust
Our scorecard separates fixes delivered, search-engine signals and business outcomes—each with its limits stated.
| Signal | What we review | What it cannot prove |
|---|---|---|
| Indexing coverage | Priority pages indexed versus submitted and excluded reasons in Search Console. | Indexing does not guarantee rankings or traffic. |
| Crawl health | Server errors, redirect chains and crawl distribution across URL patterns. | Crawl stats are sampled and vary with Google's own scheduling. |
| Core Web Vitals | Field LCP, INP and CLS by template against Google's 'good' thresholds. | Good scores are one signal among many and need enough real-user data. |
| Fix delivery | Tickets shipped, validated and regressed over the period. | Shows work completed, not commercial impact on its own. |
| Organic outcomes | Organic landing-page sessions and conversions for affected templates. | Seasonality, content and competition also affect results. |
Tool health scores are a starting point, not a goal. We report from Search Console, field performance data and analytics, and note when changes elsewhere—content, seasonality, competition—also affected results.
Grounded in official guidance
Independent Google guidance—not an endorsement of Slashside or an agency performance claim.
Google documents how robots.txt, noindex, canonicals and sitemaps influence what it crawls and indexes.
Read official guidanceGoogle treats LCP up to 2.5s, INP up to 200ms and CLS up to 0.1 as 'good'.
Read official guidanceGoogle renders JavaScript, but content and links should be discoverable in the rendered page.
Read official guidanceGoogle recommends mapping old URLs to new ones with permanent redirects when moving a site.
